2.6.14-rc1 - kernel BUG at fs/ntfs/aops.c:403

[Bas Vermeulen]

I get a kernel BUG when mounting my (dirty) NTFS volume.

Sep 12 18:54:47 laptop kernel: [4294708.961000] NTFS volume version 3.1.
Sep 12 18:54:47 laptop kernel: [4294708.961000] NTFS-fs error (device
sda2): load_system_files(): Volume is dirty.  Mounting read-only.  Run
chkdsk and mount in Windows.

Not sure what's the cause, it started after the last NTFS code update.

Ouch.  )-:  Could you do two things for me so I can figure out what is 
going on?

1) Apply this patch to fs/ntfs/aops.c:

--- aops.c.old	2005-09-15 09:51:30.000000000 +0100
+++ aops.c	2005-09-15 09:53:53.000000000 +0100
@@ -400,6 +400,10 @@ retry_readpage:
 		}
 		/* Compressed data streams are handled in compress.c. */
 		if (NInoNonResident(ni) && NInoCompressed(ni)) {
+			ntfs_error(ni->vol->sb, "Eeek!  i_ino = 0x%lx, "
+					"type = 0x%x, name_len = 0x%x.",

+					ni->name_len);
 			BUG_ON(ni->type != AT_DATA);
 			BUG_ON(ni->name_len);
 			return ntfs_read_compressed_block(page);

2) Enable ntfs debugging in the kernel configuration.

Recompile the ntfs module (or the kernel if ntfs is built in).

Then load the new module (if not built in).

Then enable debug output (as root do):

	echo 1 > /proc/sys/fs/ntfs-debug

Now do the mount and send me the resulting dmesg output.  That should 
hopefully enable me to fix it.

Thanks!

Best regards,

	Anton

The logs are below. The mount resulted in a segmentation fault.

Great, thanks!  I suspected this might be the case but I didn't think 
that was possible.  )-:

Could you confirm for me that this ntfs volume is compressed?  (I.e. the 
compression bit is enabled on the root directory.)

Best regards,

Excellent, thanks.  I will try and do the fix tomorrow and send it to

I just hit the same BUG in different conditions. My NTFS volume is not
dirty, not compressed (BTW, is there a way to tell from Linux directly?)
and the BUG triggered on use (updatedb), not mount.

I've done all this, ran updatedb and got a segmentation fault, here is
the resulting dmesg log:

There is much more debug stuff before the BUG happens but it was a bit
large to include here. Available of request.

The relevant line in /etc/fstab is:
/dev/hda1        /mnt/win/c       ntfs        gid=497,umask=0227,nls=utf8,noexec,ro        1 0

Note that I don't care about that NTFS volume myself, I don't use it,
I'm only mounting it in order to help find bugs in the ntfs driver. It
seems to work ;)

Thanks,

Same here, but it only triggers accessing a compressed directory. I can
reproduce at will just by using 'ls' inside a compressed dir.
